Analysis · SSRM · Energy & Transportation
An updated Technical Report Summary for the Marigold Complex in Nevada lifts gold Mineral Reserves by 43% to 4.63 million ounces and incorporates the maiden life of mine plan for the Buffalo Valley satellite project. The plan supports a 20-year mine life with after-tax NPV5% of $3.3 billion at consensus gold prices, average annual production of 231,000 ounces from 2027-2031, and AISC of $2,062/oz. The reserve increase is driven primarily by a higher gold price assumption ($2,200/oz vs $1,700/oz previously) plus infill drilling. Buffalo Valley adds 0.67 Moz of reserves with first production expected in 2029, contingent on securing permits. This materially extends the company's U.S. production runway and reinforces its position as the third-largest U.S. gold producer.
